Specification forming part of LettersPatent No. I 77,729, dated May23,1876; application filed March 21, 1876. p i v To all whom itmayconcern v Be it known that I, JAMES L. LORING,of DallasUentre, Dallascounty, Iowa, have invented a new. and Improved Stove-PipeJoint, ofwhich the following is a s 'iecification Figure 1 representsai'verticalcentral sec; tion on' line 0 0,'Fig. 2, of my improved stoveand Fig. 2is a horizontal section of the same. p

Similarletters of reference indicate corresponding parts.

My invention relates to an improved stovepipe joint that forms a solidand firm connection ot'the pipes, so that they cannot be pulled apart orpushed together, while being'i'eadily disconnected when required.

The invention consists of slots or recesses atthe end of one pipe, inconnection with rivets or studs of the other pipe end, the

rivets having broad interior heads, and shanks nearly of the width ofthe slots. p

In the drawing, A and B represent the stovepipes that are to beconnected. The end ofthe Stovepipe A slides into theiend of pipe B, andlocks, by two or more slots or recesses,

C, on studs or rivets D of vpipe B. The re cesses G aremade of curved orL shape, and extend from the edge inwardly to guide the rivets D,'Whichslide by their shanks, having nearly the width of the slots, up to theends of the same, and bind by broad heads on' the inner pipe, and lockthe pipes securely together.

The outer and thinner ends of the rivets D areapplied to small holes ofthe pipe B by means of the shanks that form shoulders bearing on thepipe, and byflattening the outer ends of the rivets, the stove-pipes arequicklydetached by turning the outer pipe so that the rivets move backin the slots and discontinue the. interlocking with the slots.

Having thus described my invention, Iclaiin as new and desire to secureby Letters Patcurved slot 0, and broad-headed stud D, as p shownanddescribed.
